Abstract: The specitic heat of the hyperfine enhanced nuclear magnetic system PrNi$_{5}$ has been measured from 0.2 mK to 100 mK and in magnetic fields up to 6 T. The system was found to order at (0.40 $\pm$ 0.02) mK. From the study of the measured thermodynamic quantities in various magnetic fields, we obtain various information, the order at T=O K is ferromagnetic, the hyperfine enhancement factor 1+K=(12.2 $\pm$ 0.5), the enhanced nuclear magnetic moment is (0.027 $\pm$ 0.004)$\mu$B and a nuclear exchange parameter $\sum_{j}$ k$_{ij}^{N}$/k$_{B}$=(0.20 $\pm$ 0.04) mK. The nature of the interactions which cause the ordering is discussed, together with the magnetic properties of the system deduced from the analysis.
